It talks about how much data might be generated (4,000 GB per day), how that sheer volume will be handled, and how it might be monetized. And the challenges of cybersecurity and privacy.

Auto makers are well aware of the privacy issues. Challenges will include how to deal with privacy laws that vary dramatically around the world. Will they default to the highest standard? Or will the data be valuable enough to make it worth their while to deal with information differently in different countries?

How will auto makers give drivers comfort that their information will be secure and won’t be misused? How will they explain what info will be anonymized, and what will remain identified with the driver?

How many drivers will not be eager to share driving info with insurers and others either for privacy reasons or skepticism about what arbitrary decisions about them will be made based on that info?
